"He has been training particularly hard and is very, very fit and raring to go," Tietjens said. "That's exactly where I wanted him, because he has that vital experience - he has been to Commonwealth Games. But at the same time, before he got injured, he was playing very well.
"DJ knows the game inside out. And the game has changed since 2010 [when New Zealand won Commonwealth Games gold in Delhi] - it's changed so much - but DJ has continued to play the game and conditioning-wise he is in fantastic condition at the moment. I'm looking for big things from him because he proved to me what he can do.
When we won in Canada he was simply outstanding, when we [made final] in Hong Kong, unbelievable, and again I'd expect no different going to Rio."
New Zealand's point of difference at Rio will be their size, power, and willingness to make life difficult for their opponents at the breakdown.
Other nations don't compete much there, preferring instead to put more bodies in the defensive line than the ruck, but New Zealand under Tietjens make their opponents work for every possession. And in the middle of it all, with his gleaming bald head and bushy miner's beard, is Forbes.
He stepped down as captain last year in order to concentrate on getting to Rio. Now he is nearly there and he will be leading from the front.
